EF0 tornado, Elliott, Texas, May 8, 2019

This EF0 tornado ran 0.3 miles across Robertson County on May 8, 2019, touching down at 1:29 PM CDT and reaching 100 yards wide. It killed nobody, and did $10,000 of property damage.

The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. EF065 to 85 mphthis tornado

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. EF2111 to 135 mph

    Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

  4. EF3136 to 165 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. EF4166 to 200 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. EF5over 200 mph

    Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

  7. Unrated

    The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

The damage survey

5 damage points were recorded along this path by NWS FWD, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 85 mph.

  • Metal RV cover was knocked down and beams were bent at the ground. Parts of metal roof were blown off into field.
  • Straightline winds lifted the porch covering and peeled the metal and wood roof off a log-cabin home. A large tree was also damaged on the property
  • Several scattered trees were uprooted, snapped or experienced some limb damage along Harless Road.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

What the Weather Service recorded

A complex of thunderstorms produced isolated areas of flash flooding Wednesday morning as it moved in from the northwest. Storms weakened around midday, but redeveloped across the southern counties Wednesday afternoon. One of these storms produced a brief tornado in the Elliott area of Robertson County.

A weak tornado occurred in the Elliot area within a larger area of straightline winds. The tornado damaged a large metal barn and trees along a quarter mile path to the east. Additional damage in the area was determined to be straightline winds associated with a bowing segment and/or a rear flank downdraft. The maximum winds of the tornado were estimated at 85 mph.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

The warnings

17 minutes of warning. NWS FWD issued a tornado warning for this county at 18:12 UTC, 17 minutes before the tornado touched down, in force until 18:45 UTC.

The county was under a severe thunderstorm watch, issued at 17:58 UTC and running to 20:40 UTC.

.AVIATION...
/18Z TAFs/

Winds became easterly and with gusts up to 30 knots just behind
the back edge of the line of thunderstorms. KAFW and KFTW have
since become variable, and this trend is expected to continue at
KDFW, KDAL, and KGKY as the system continues to track eastward.
Winds should slowly shift to southerly or southeasterly by the
late afternoon hours. The blanket of cloud cover associated with
the storm system will continue to move east this afternoon with
VFR prevailing and maybe a few low clouds.

Abundant moisture will remain in the lower levels of the
atmosphere, and high res guidance is in agreement on stratus
returning by 08-09Z at ACT and 11-12Z at the Metroplex sites.
There is a possibility for IFR ceilings, but at this time
only prevailed MVFR ceilings with a mention of scattered IFR
ceilings. Some guidance has hinted some scattered showers
developing north and west of the Metroplex TAF sites Thursday
morning, but confidence is too low to mention with this issuance.
We'll continue to monitor guidance and adjust as needed in
subsequent TAF issuances. A cold front is expected to slide across
the Metroplex sites by mid morning and by early afternoon at ACT.
VFR should prevail by the early afternoon hours across the TAF
sites.

.MESOSCALE UPDATE... /Issued 1008 AM CDT Wed May 8 2019/
A moist and unstable airmass remains in place south of an outflow
boundary currently extending along a line from Athens to Hillsboro
to Goldthwaite. A line of thunderstorms propagating eastward
along and south of this boundary will continue to have the
potential to produce damaging wind gusts and large hail.
Will need to monitor the position of the warm sector, as a
northward shift would extend the severe storm potential a little
farther north, but at this time it looks like ongoing convection
along the I-20 corridor will likely keep the surface boundary near
its current position through early afternoon. In addition to the
hail and wind threat, 0-1 KM storm-relative helicity values
between 150 and 200 m^2/s^2 when combined with surface-based CAPE
around 2000 J/KG indicates that at least a low-end tornado threat
will exist, which would likely be of the QLCS variety along the
ongoing squall line if one were to occur.

North of the outflow, the primary concern will be localized flash
flooding due to west-east training of thunderstorms. Occasional
rainfall rates around 2 inches per hour can be expected along and
north of the surface boundary, putting the near-term threat for
additional flooding immediately south of the I-20 corridor. These
storms will continue to shift east with time, extending the heavy
rain threat eastward from Johnson and Ellis Counties to Kaufman,
Henderson and Van Zandt Counties between now and early afternoon.

As far as the rest of the forecast, POPs have been adjusted and
the high temperature forecast has been lowered based on recent
trends.

.SHORT TERM... /Issued 239 AM CDT Wed May 8 2019/
/Today and Tonight/

A quasi linear convective system (QLCS), currently forming just
off the Caprock, will move east across the region today, bringing
a potential for damaging winds, hail and even a brief tornado or
two. Periods of heavy rainfall will also be likely which may
result in localized flooding. However, the progressive nature of
the line should keep the threat of widespread flash flooding
relatively low. The convective allowing models are falling into
fairly close agreement with regards to timing and placement of the
main line with storms reaching the western zones before sunrise,
the I-35 corridor between 8 AM and 10 AM, and the eastern zones
late morning through early afternoon. A few strong to severe
storms will also affect the western zones prior to the arrival of
the main line with damaging winds the primary hazard. These
leading storms should weaken as they reach the US 281 corridor
when they encounter stronger convective inhibition. Once the main
line of storms moves through, clouds should begin to decrease from
west to east, allowing temperatures to warm into the upper 70s
and lower 80s. The only exception will be the eastern zones where
a later arrival of storms and extensive cloud cover will keep high
temperatures in the middle 70s.

Storm chances will linger this evening, mainly in the east. The
remainder of the forecast area will likely remain dry through the
overnight hours until a cold front arrives across the northwest
zones in the predawn hours Thursday. Overnight temperatures will
range from the middle 50s across the northwest to the lower 70s in
the southeast zones.

.LONG TERM...
/Thursday through Tuesday/

A cold front will slide across North Texas Thursday morning as a
shortwave lifts across Central Plains. Initially the front will
come through dry with limited moisture to work with after today's
storms. However, some thunderstorms should begin to fire in the
afternoon as the front moves into the southern zones where
moisture and instability will be much more favorable. It looks
like the best severe threat will be just southeast of the forecast
area.

Weak cold air advection and some lingering clouds behind the cold
front will keep temperatures below seasonal normals with highs
generally in the upper 60s and 70s. The only exception will be
some lower 80s across the southeast zones.

Thunderstorms will temporarily move south of the forecast area
Thursday evening, but may develop across the southern zones again
overnight Thursday/Friday morning as moist air is lifted over the
shallow wedge of drier/more dense air near the surface.
Confidence is low in exactly how far south the cold front will
move Thursday night, therefore, we will keep PoPs low for now.

The cooler and drier airmass will remain largely unchanged Friday
with dry northeasterly surface flow. The combination of low level
cold air advection and extensive high clouds associated with a
deepening upper low on the West Coast will result in a cool day
for May with morning lows in the upper 40s and 50s and highs
mainly in the middle and upper 60s.

Rain and thunderstorm chances will slowly increase Friday night
and Saturday as a few northeastward moving shortwaves traverse the
region. The best moisture will remain across Central Texas which
is where we will keep the highest PoPs. It will remain cool with
morning lows Saturday generally in the 50s and highs from the mid
60s to the lower 70s.

The upper low will begin to lift northeast across the Desert
Southwest Sunday/Sunday night, resulting in brief ridging aloft
over North and Central Texas. Decreasing clouds and waning cold
air advection will result in warmer temperatures Sunday with
highs in the 70s and lows Sunday night in the mid and upper 50s.

Low level moisture will finally return to the region Monday
through Tuesday as the low pressure system begins to weaken and
lift northeast towards the Central Plains. The increase in
moisture and large scale lift will result in scattered showers and
thunderstorms with the best chances across the southwestern half
of the forecast area. The moisture increase will also bring more
seasonable temperatures with lows in the upper 50s and 60s and
highs in the upper 70s and lower 80s.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
